A recent change to the upstream descriptor.proto, appearing in
google.golang.org/protobuf@v1.33.0, removed the long-deprecated
FileOptions.php_generic_services field. This backwards-incompatible
change results in an incompatibility between the
github.com/golang/protobuf and google.golang.org/protobuf
modules.
Bump the google.golang.org/protobuf version in go.mod, regenerate
descriptors.
Increase the minimum Go version requirement to go1.17 (the minimum
supported by v1.33.0).
Run gofmt to update formatting to go1.22 standards.
For #1596
